SPECIFICATION forming part of Letters Patent No. 394,223, dated December11, 1888. Application filed October 20, 1888. Serial No. 288,675. (Nomodel.)

.To LLZZ whom may concern:

Be it known that I, WALTER JUDsoN STE- VENS, a citizen of the UnitedStates, residing at IVhitesviIle, in the county of Allegany and State ofN ew York, have invented new and useful Improvements in Olivers, ofwhich the following is a specification.

My invention relates to improvements in olivers; and it consists incertain novel features hereinafter described and claimed.

The primary object of my invention is to provide means whereby thehammer can be readily adjusted to work upon any desired part of theanvil.

A further object of the invention is to improve the construction of thedevice, whereby it can be more easily and rapidly operated than thedevices heretofore employed.

These objects I accomplish by the use of the mechanism illustrated inthe accompanying drawings, whereinn Figure 1 is a side elevation of anoliver. 2 is a front view showin the manner of adjusting the hammer toplay on different parts of the anvil. Fig. i is a detail perspectiveview of the rock-shaft.

Referring' to the drawings by letter, A designates the anvil, sujrportcdupon a suitable base, B, of the usual or any preferred constructioi'i.From 011e side of the base a pin, C, projects laterally, the purpose ofwhich will presently appear, and to the same side of the base, adjacentto the said pin, I secure a guide, D, which will be presently more fullyreferred to. At a suitable distance from the base I erect the standardsE E, which are connected by a cross-brace, F, as shown, and havebearing-boxes G secured to their upper ends. A rock-shaft, H, isjournaled in the bearing-boxes G, and has one end projected beyond theadjacent bearing-box and provided with a crank-arm, I.

J designates the operating foot-lever, which is pivoted at one end tothe side of one of the standards E, and extends forward from its pivotthrough a guide, K, secured to the side of the said standard, to a pointnear the front side of the base B, where it is widened laterally to forma foot-rest or pedal, L, as shown. The front end of this operating-leverplays in the guide D, the said guide and the guide K securing a truevertical movement of the lever in operation. A spring, II, is secured tothe upper side of this lever, and its free end is adapted to contactwith the pin C, projecting from the base, so as to serve as a buffer andstop to limit the upward movement of the lever and deaden the force ofthe contact between the lever and the said pin.

N designates a connecting-rod having its lower end pivotally secured tothe operatinglever and its upper end engaging one of a series oftransverse openings, O, in the crankarm I of the rock-shaft. By thisconnection, when the lever is depressed, t-he rock-shaft is rotated, aswill be readily understood, and the hammer thereby brought down upon theanvil, and the blow given by the hammer can be varied by causing theupper end of the connecting-rod to engage one or another of the openingsO, as will be readily understood.

P designates crank-arm formed integral with 'the rock-shaft andprojecting rearward therefrom at aboutthe center of the same, andprovided with a series of transverse openings, Q, one of which isengaged by the upper end of a spring', R, which has its lower endsecured to the lHoor of the shop or any other fixed point. This sprinserves to return the roclcshaftto its normal position and raise thehammer, after the same has been brought down upon the anvil, by means ofthe operating-lever and connecting-rod, as above referred to.

S designates a sector-plate formed integral with and projecting upwardfrom the rocksha-ft, and having a series of notches, T, in its uppercurved edge, as shown. The hammer U is pivoted to the sector-plate bymeans of a pivotal bolt, V, passed transversely through the said plateand the end of the hammer, as shown. A sliding latch, IV, is mounted onthe handle of the hammer, and

the end of the same engages the notches T of the sector-plate to lockthe hammer in the desired position. The said latch is held normally inengagement with the said notches by means of a coiled spring, X,arranged around the latch between a pin, Y, inserted transverselythrough the same and a lip, Z, at the end of a casting, a, the saidcasting being provided at its opposite end with a tongue, h, which ridesover the curved edge of the IOO sector-plate and thereby prevents theend of the latch moving laterally from the notches. The lip Z and thesaid tongue b serve, also, to guide the latch into the notches, as willbe readily understood. In order that the latch may be disengaged fromthe notches, I provide the free end of the same with a spur or handle,c, as shown.

Such being the construction and arrangement of the parts of my device,the operation and advantages of the same will be readily understood.

The metal to be operated upon is held upon the anvil in the ordinarymanner and the smith operates the device by depressing1 the lever withhis foot. The hammer is thus brought down upon the metal, as willbereadily understood, when the pressure on the lever being removed thespring automatically returns the hammer to its normal raised position topermit the meta-l to be turned or otherwise shifted, as may be required.\Vhen it is desired to work the metal at the center of the anvil, thelatch on the handle of the hammer is engaged in the central notch of thesector-plate, as shown in Fig. 1. Then it is desired to work the metalupon the horn or the heel of the anvil, the latch is disengaged from thecentral notch and the hammer is then swung upon its pivot to one side orthe other and the latch engaged with one of the notches to hold thehammer in its adjusted position. The device is then operated in themanner before described, as will be readily understood.

It will be observed from the foregoing' description, taken in connectionwith the accompanying drawings, that I have provided a very simpledevice, which is composed of few parts, which is free of all complicatedcombinations and arrangements, and which can be manufactured and sold ata smal cost.

I-Iaving thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-- l. In an oliver, the combination of therockshaft, the sector-plate projecting therefrom,

the hammer pivoted to said sector plate, mechanism for locking thehammer to the said plate, and mechanism for rotating the rockshaft,substantially as set forth.

2. The combination of the rock-shaft, the sector-plate projectingtherefrom, the hammer pivoted 011 the sector-plate, the latch mounted onthe handle of the hammer and engaging said sector-plate, and mechanismfor rotatin g the rock-shaft, as set forth.

The combination of the rock-shaft having a crank-arm projecting from itscentral portion, the sector-plate projecting from the said shaft, thehammer pivoted on the said sector-plate, the latch mounted on the handleof the hammer and engagin said sectorplate, the spring secured to thecrank-arm of the rock-shaft to rotate the same in one disection, andmechanism for rotating the rockshaft in the direction contrary to thatof the spring, as set forth.

4. In an oliver, the combination, with the base B, having the pin Cprojecting laterally from one side, of the operating-lever having aspring secured to its upper side and adapted to contact with said pin,as set forth.

5. The combination of the standard, the rock-shaft mounted on the upperends of the same and having a crank-arm, I, at one end and the crank-armI) at its center, the spring secured to the crank-arm P, the hammercarried by the rock-shaft, the lever pivoted at one end to the side ofone of the standards and projectingforward beyond the same, and theconnecting-rod having its lower end pivoted to the lever and its upperend adjustably secured to the crank-arm I, as set forth.

G. The combination of the rock-shaft, the sector-plate projectingtherefrom, the hammer pivoted on the sector-plate, the casting havingthe tongue I; riding over the edge of the sector-plate, the latchengaging the sector-plate, and the spring coiled around the latch andadapted to hold the same normally in engagement with the sector-plate,as set forth.

7. The combination of the standards, the rock-shaft mounted thereon, thehammer carried by the rock-shaft, the guide K, secured to the side ofone of the standards, the base having the pin C and the guide y D on oneside, the operating-leverpivoted to the standard and projecting forwardthrough the guides K and D, the spring secured to the upper side of thelever and adapted to contact with the pin C, and the connecting-rodextending vbetween the lever and the rock-shaft, as specifled.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
